FIREPBOOF SWING AND VENTILATOR.

To all whom it may concern:

Be it known that I, DANNIEL M. Craven, Sn, a citizen of the UnitedStates, residing at Paducah, in the countyof Cottle and State of Texas,have invented certain new and useful Improvements in Fireproof Swingsand Ventilators, of which the following is a specification.

My invention relates to new and useful improvements in chimneyconstructions, the primary object of my invention being the provision ofa fireproof ventilated swing for the chimney base.

In many instances, in order to economize in space or prevent thebuilding of unsightly abutments in lower rooms, it is found advisable tobuild a chimney the base i of which is supported upon the ceilingtimbers or the upper joists, the smoke or other products of combustionfrom a stove or furnace passing into the lower end of theChimney-through a sheet metal flue or flue of other suitable material.One of the primary objects of this invention consists in constructing aswing for supporting the'base of a chimney of this character in such amanner that the weight of the chimney will be evenly distributed betweena number of the ceiling joists and a-number of the roof supportingrafters in order that any sagging of the ceiling may be prevented.

- A still further object of my invention consists in constructing theswing in such a manner that the base of the chimney is projected betweenthe ceiling joists and lies I unearly flush with the ceiling itself, sothat the flue leading to the chimney need not pass through any woodwork.

.In this connection, a stlll furtherobject vof my invention consists inthe provision of a sheet metal ventilating flue which is built into thelower open end of the chimney to receive the flue leading from the stoveor other heater so as to provide a fireproof air space about the upperportion of the flue proper.

Other and incidental objects will appear as the description proceeds andin the drawings wherein I have illustrated the preferred embodiment ofthe invention and wherein s1m1lar, reference characters designatecorresponding parts throughout the several views,

tion of a chimney and its swing constructed in accordance with myinvention,

Fig. 2 is a plan view of the ceiling timbers with the swing in place andshowing the parts before the chimney itself is applied,

Fig. 3 is a perspective view of the body portion proper of the swing.

Fig. 4 is a central vertical sectional view of the ventilated flueportion of the chimney base.

In order to insure a clear and accurate understanding of my invention, Ihave illustrated my chimney construction in connection with a pluralityof parallel ceiling supporting joists 10 to the lower edges of which aresecured the usual laths 11 carrying the plastering 12 making up theceiling proper of an upper story room. Secured to the upper edges ofthese joists is a supporting frame including side sills 13 andintermediate shorter sills 1 1, the ends of which are spaced to define asquare opening between the inner ends of the intermediate sills 14 andthe sides of the side sills 13 in which space the chimney swing and baseare to be located. Preferably, any suitable bracing means, such as anumber of boards or longer timbers 15. are connected to the joists 10and extend vertically with their upper ends connected to the roofcarrying rafters, not shown, to provide braces for the roof and ceiling.Because of this, any strain exerted upon the frame 13 will bedistributed over a considerable portion of both the ceiling and rooftimbers and any sagging of the ceiling because of the weight of thechimney is thereby prevented.

Supportedin the square space provided within the frame is the swingproper 16 which carries both the ventilating flue 17 and the chimneybase 18. This swing proper is best shown in Fig. 3' of the drawings and.is formed of iron bars cut to the proper dimensions and bent to thedesired shape. More particularly, this swing includes a square outerframe made up ofspaced side bars 19 upon which aresecured spaced endbars 20, both the side bars and end bars having upwardly directed ends21 the terminals of which are outwardly bent as shown at 22 to rest uponthe upper face of the frame formed by the sills 13 and 1 1. The bars 19and 20 are secured by'rivets 23 ,or other su t le fastening means andbolts 24 may 25 are riveted to theunder faces of the end bars 20 andinner end bars 26 are riveted to the upper faces of the sidebars 19,these inner bars being then riveted to each other, with-' the resultthat-inner and outer square frames are formed. The upwardly directed endportions 21 of the swing bars are so pro"- portioned that when the swingis in place, the bars proper will rest almost flush with thelathsconstituting a portion of the cell- Disposed centrally within" the swingthus formed is the ventilated flue 17. This fine includes, an outercylindrical shell 27 of sheet metal, preferably relatively heavy sheetiron and an inner cylindrical shell or'flue portion 28. of less diameterthan the outer shell to provide an annular air chamber 291, The innershell at its upper end is formed with a laterally. directed peripheralflange 30 which; projects beyond the outer shell and the free edges ofthis flange and the upper edge of the outer shell are bentto provideinterlocking'seams 31 by meansof which the two shells are securedtogether and the inner shell he'ld in centralized position with respectto the outer shell. In like manner, the -:innershell at its lower end isformed with a peripheral flange 3'2 wli-ifch engages against the lowerface of an outwardly directed peripheral flange 33 of the outer shelland the free edge of the flange 32 is peen'ed and soldered over theflange 33 as clearly shown. This flange 32 isprovidecl with a pluralityof peripherally spaced openings '34 communicating with the chamber 29inorder that there may be a free circulation of; air

2 in this chamber.

The external diameter of the interlocking .fla'ng'es 32 and is greaterthan the distance between the bars of the inner frame of the swing whilethe; external diameter of the "outer shell 27 .is slightly less thanthe, dist'ance between'the bars of the inner frame of the swing.In'constructing a chimney in accordance with my invention,- thesupporting frame is first made and the swing secured in place, asuitable opening having been formed in the ceiling. The ventilated fine"17' is'th'en'passed upwardly through the opening in the ceiling andbetween the bars of the inner fram'e of'the swing untilits flangeengages the bars as sh'own in Fig. 2. "Itisthen'supportedin place bybending over the free ends of 'diametrieally disposed hanger strips- 35-formed of sheet metal and The upwardly 36 forming the base of thechimney 18 and built up in "regular courses in the :usual manner, thebricks of course being embedded in mortar and forming a square housingabout .the flue 17 After severalcourses of bricks tinned toprovide anannular deflecting'ring or spout 37 through which any soot depositedfrom smoke and other products of combustion passing through the chimneywill be directed intothe flue-l7 and so to the flue leading from thestove. @f' course, after the base portion of the chimney isv constructedin the hanger and the strips 35 have been embedded therein, theremainder of the chimney is built up and extended through a suitableopening formed in the roof in'the usual manner. With a chimney of thischaractor, a sheet metal flue is led from the" stove or furnace and hasits end fitted into the lower end of the ventilated flue 17, a suitablethimble ring being employed at this point, if desired.

As will be noticed by reference-to Fig. 1, the flange 32 of theventilated flue will lie flush and in effect, form a-continuationof theplaster of the ceiling in order'to present a neat appearance in: theroom below. If pre ferred however, or if required by fire insuranceunderwriters theswing may be so 9 proportioned as to extend somewhatbelow the ceiling of the room inorder to still further remove the sheetmet'al'flue from all woodwork of the ceiling.
